CWE-943: Improper Neutralization of Special Elements in Data Query Logic
Depending on the capabilities of the query language, an attacker could inject additional logic into the query to:
- Modify the intended selection criteria, thus changing which data entities (e.g., records) are returned, modified, or otherwise manipulated
- Append additional commands to the query
- Return more entities than intended
- Return fewer entities than intended
- Cause entities to be sorted in an unexpected way
The ability to execute additional commands or change which entities are returned has obvious risks. But when the product logic depends on the order or number of entities, this can also lead to vulnerabilities. For example, if the query expects to return only one entity that specifies an administrative user, but an attacker can change which entities are returned, this could cause the logic to return information for a regular user and incorrectly assume that the user has administrative privileges.
While this weakness is most commonly associated with SQL injection, there are many other query languages that are also subject to injection attacks, including HTSQL, LDAP, DQL, XQuery, Xpath, and "NoSQL" languages.
